Ali G In Da House is a comedy with alot of adult content but is a prime example of a stereo typical 'Gangster' movie.
The opening has back and fourth flashes while the setting is being displayed, this shock factor disturbing the human eye, argumentatively hypnotises the audience into watching more.
The main character is shown to the audience as a bit of a clown with his bright yellow and orange gear on. He is instantly funny making the viewers fall in love with him, come on now who doesn't like a good laugh!
